IMPROVEMENT IN LUBRICATORS FOR AXLES AND OTHER SPINDLES.

Specification forming part of Letters Patent No. 120,515, dated October 31, 1871.

To all whom 'it may concern:

Be it known that I, WILLARD H. HARVEY, of Bangor, in the county of Penobscot and State of Maine, have invented a new and valuable Iniprovement in Lubricators; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and gures of reference marked thereon.

Figure 1 of the drawing is avertical section of my invention.

This invention has relation to axle-lubricators; and the novelty consists in the construction and arrangement of an apparatus having a reservoir for oil or grease, and a syringe for projecting it along the surface of the spindle, as hereinafter described.

Referring to the accompanying drawing, which illustrates this invention, A represents the spindle of an axle; B, a wheel-hub; C, an orifice in the hub leading to said spindle; D, pivoted plate, designed to cover said orifice. E designates a cylindrical cup or reservoir adapted to contain lubricating oil, with which it is supplied through a tube, E1, having a cover or cap, E2. Within said reservoir is arranged a syringe-tube, F, terminating at its lower end in a narrow stem, F', which lits the orifice C, into which it is inserted to oil the spindle. G designates the piston of the syringe; H, an aperture/by means of which the tube F and reservoir E communicate, and through which oil is conducted from the latter to the syringe.

The lubricator is applied to the spindle and the oil injected as if with an ordinary syringe.

I claim as my invention- The lubricator herein described, having the reservoir E, syringe F, comlnunicating orifice H, and piston Gr, as and for the purposes specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
